如何用for循环产生水平和垂直线？

Question

So this is my class. I'm trying to get the print() method to print out a horizontal line above my array and another line below my array. I also want to have vertical lines between each number in my array. Okay, I fixed my horizontal lines. Now I'm just lost on how to put vertical lines at the beginning and the end of my arrays.

public class Array{

private int[] array;

public Array(int numElements)
{
    array = new int[numElements];
}

public void fill()
{
   for (int i = 0; i < array.length; i++)
    {
        array[i] = (int) (10*Math.random());
    } 
}

public void print()
{
    for(int x = 0; x < 2*array.length; x++)
    {
        System.out.print("-");
    }
    System.out.println();

    for(int i = 0; i < array.length; i++)
    {
        System.out.print(array[i]);
        if(i == array.length - 1)
        {
            System.out.println();
        }
        else
        {
            System.out.print("|");
        }
    }

    for(int n = 0; n < 2*array.length; n++)
    {
        System.out.print("-");

    }
    System.out.println();
}

public void sort()
{
    int n = array.length;
    boolean swapped;

    do
    {
        swapped = false;

        for(int i = 1; i < n; i++)
        {
            if(array[i-1] > array[i])
            {
                int tmp = array[i];
                array[i] = array[i-1];
                array[i-1] = tmp;
                swapped = true;
            }
        }
    } while(swapped);
}

public void printFrequency()
{
    int[] countArray = new int[10];
    for(int x : array)
    {
        countArray[x]++;
    }
    for(int i = 0; i < 10; i++)
    {
        System.out.println("There are " + countArray[i] + ", " + i + "'s ");
    }
}
}

This is my output:

1|5|9|3|3

Answer 1

Move the line System.out.println(); outside of your for loop if you don't want to create a new line after each dash character.

Answer 2

take the println() out of this loop :

for(int n = 0; n < array.length; n++)
{
    System.out.print("-");
    System.out.println();
}
